With reference first to Fig. 1 and Fig. 2, they show floor side member according to an embodiment of the invention from different angles
Reinforcer 1.Floor side member reinforcer 1 includes the reinforcer main body 10 that is made up of extrusion, reinforcer main body 10 have be used for it is rear
The first end 19 of longeron main body connection and the second end 18 for being connected with back buffer beam main body.Collided in vehicle, especially
When its vehicle tail collides, reinforcement between floor side member main body and back buffer beam main body, being made up of extrusion is arranged in
Part main body 10 will occur the deformation of stacking shape during collision, and collision energy is converted into the deformation energy of extrusion, thus inhale
The energy produced during collision is received, slows down the infringement that collision is caused to vehicle and occupant.Term " extrusion " herein means
It is the part produced by extrusion forming, they generally comprise the side wall of unlimited two ends and closing, and optionally middle part is horizontal
To rib wall.In certain embodiments, reinforcer main body 10 can especially aluminum extrusions be formed by metal extrusion, can so be reduced
Vehicle weight.Additionally, for the floor side member that die casting is constituted, its structure is more complicated, while in order to after meeting and being close
Performance is touched, it is necessary to form enough intensity than larger envelope, interior space will be compressed；And for the floor side member of stamping parts composition
For, then weight is larger.The application, as floor side member or a part for back buffer beam, is sealed using extrusion because extrusion has
The section closed, section power and section rigidity are larger, therefore can have relatively small envelope, thereby increase the available sky of vehicle
Between.
In certain embodiments, floor side member reinforcer 1 also includes being arranged on the peace at the second end 18 of reinforcer main body 10
Dress plate 11.Installing plate 11 may be coupled to be integrally formed on the second end 18, or with reinforcer main body 10.In this example
In, installing plate 11 is made up of alumina-base material and the second end 18 of reinforcer main body 10 is connected to by such as mode such as welding.At this
In example, the whole cross section at the end 18 of the covering reinforcer of installing plate 11 main body 10 second, and continue to stretch out, it is convex so as to form
The periphery 16 gone out to beyond the cross section of the second end 18 of reinforcer main body 10.According to the present invention, be disposed with installing plate 11 for
The reinforcer main body 10 is connected to back buffer beam（It is not shown）Installation portion, it may be provided at any appropriate position of installing plate 11
Put, this is specifically dependent upon the mechanism of back buffer beam in practical application.In a specific example of the invention, in installing plate 11
It is disposed with periphery 16 for the installing plate 11 to be connected into back buffer beam（It is not shown）Mounting hole 12, as will strengthen
Part main body 10 is connected to the installation portion of back buffer beam.Here, example and without limitation, installing plate 11 is substantially square, and at this
In concrete application, the middle part on square every one side is shunk towards the direction of reinforcer main body 10 slightly, and described mounting hole 12
It is arranged on four angles of the installing plate 11.It should be noted that the shape of installing plate 11 is not with herein with reference to accompanying drawing institute
Description be shaped as limitation, it will be understood by those skilled in the art that the shape of installing plate 11 can according to it is connected for example after
The shape of the components such as collision prevention girders main body determines.
In certain embodiments, floor side member reinforcer 1 also includes being used for setting the body junction to car in reinforcer main body 10
For the support member 5 of support reinforcement main body 10 when within structure.Support member 5 can be extended by reinforcer main body.The of support member 5
Side 51 is connected to vehicle body sheet metal, the second side（Do not indicate）The bottom of support reinforcement main body 10, it should be appreciated that the second side and first
Side 51 is located at the both sides of support member main body 50.The setting of support member 5 cause floor side member reinforcer 1 with floor side member main body and rear defence
Beam main body is hit to connect and can be supported without hanging when being attached to vehicle body.
Fig. 3 is the sectional view of the reinforcer main body of floor side member reinforcer according to an embodiment of the invention, with reference to Fig. 3
Reinforcer main body 10 is expanded on further.Reinforcer main body 10 includes roof 101, left side wall 102, bottom wall 103 and right side wall
104, they are sequentially connected the perisporium for constituting reinforcer main body 10.Further, have at each angle of the perisporium of reinforcer main body 10
Angle 108, and reinforcer main body 10 also includes cross rib wall 105, its middle part for being arranged on left side wall 102 and right side wall trench 104.It is left
Intersection of the side wall 102 at it with middle part cross rib wall 105 inwardly, the direction namely towards right side wall 104 it is recessed, form left
Sidewall channels 107；Accordingly, intersection of the right side wall 104 at it with middle part cross rib wall 105 inwardly, namely towards left side arm
